SPECIFICATION forming part of Letters Patent No. 550,623, dated December3, 1895. Application filed June 3, 1895. Serial No. 551,546. (N0 model.)

To LZZ whom it may concern:

Be it known that l, FRANK KRUPP, a citizen of the United States,residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented certain new and useful Improvements inShutter-Fasteners and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in that class of shutter-fastenerswhich comprise a rod extending through the sill of a windowcasing andhaving a head at its outer end adapted to engage a keeper in the outerinember vof a pair of shutters or blinds; and its novelty and advantageswill be fully understood from the following description and claim, whentaken in conjunction with the accompanying drawings, in which- Figure 1is a vertical section illustrating a portion of a window-casing and ashutter 0r blind equipped with my improvements. Fig. 2 is a sectiontaken in the plane indicated by the line a: a; of Fig. l;Y Fig. 3comprises detail perspective views of several parts hereinafter referredto.

Referring by numerals to the drawings, 1 indicates the sill, 2 thesub-sill, 3 the stool, and 4: the apron, of awindow-casing, all of whichmay be of the ordinary form and construction.

5 indicates a shutter or blind which has its free vertical edgerabbeted, as shown in Fig. 2, to form a portion 6, designed to rest inthe rabbet 7 of its fellow shutter 8 when the shutters are closed, sothat the shutterS cannot be swung open until after the shutter 5 isopened.

9 indicates a recess which is formed in the inner side of shutter 5,preferably at a point adjacent to the free vertical edge of the same.

10 indicates a countersink-plate which is secured by screws or the likein the shutter 5 over the recess 9, and is provided with an elongatedslot 11 for a purpose presently described, and 12 indicates a passagewhich is bored or otherwise formed in the sill 1, subsill 2, and apron 3of the window-casing and extends from the inner side of said apron tothe outer edge of the sub-sill, as shown. The said passage 12 'ispreferably pitched downwardly and inwardly, as shown in Fig. 1, so

as to bring its inner end below the stool 3, and it has the said innerend closed by an escutcheon 13, which preferably comprises two sectionshaving their contiguous ends recessed, as indicated by 14, to form asquare or round opening for a purpose presently pointed out, while itsouter end is closed by the casting 15, having the vertical slot 16 andalso having the recess 17 in its outer side, and the plate 18, which iscountersunk in the outer edge of the sub-sill 2, and secured thereto, soas to rest in the recess 17 of the casing 15, and is provided with anelongated slot 19, which extends at right angles to that of the casting15.

20 indicates the locking-bolt of my improved lock, which is preferablyof a circular form in cross-section, and is provided at its inner endwith a head 21, forming a convenient iinger-piece," through the mediumof which it may be turned, and is also provided at its outer end with aT-head 22, which is preferably beveled, as shown, so as to facilitateits passage through the slot 11 of the shutter-plate 10.

` The heads 21 22 of the bolt 20 may be, and preferably are, formedintegral with the body thereof, and for this reason and to avoid thenecessity of forming a slot sufliciently large to permitthe passage ofthe head 22 the escutcheon is formed in two sections, as beforedescribed, with the small central opening which forms a tight-iittingbearing for the bolt and prevents lateral movement thereof. The casting15 of the plate 18 at the outer end of the passage 12, is provided withslots 16 and 19 larger than the bolt-head 22, so as to permit of thesaid head being formed integral with the body of the bolt; but thedisposition of the said slots at right angles to each other preventslateral motion of the bolt--that is to say, the walls of the slot 16 incasting 15 prevent lateral motion of the boltbodyin the slot 19 of plate18, while the walls of said slot 19 prevent lateral motion of thebolt-body vin the slot 16 of said casting 15.

In assembling the parts of the device the bolt 20 is first passedthrough the passage 12, after which the casting 15`is slipped over thehead 22 of the bolt and adjusted to the position shown in Figs. 1 and 2.The plate 19 is then placed in the recess in the outer edge IOO of thesub-sill 2 and in the recess 17 of casting 15, after which theescutcheon 13 is secured to the apron in the manner described, so as toform a bearing for the bolt and limit the outward adjustment of thesame.

In using the devicea person may with one hand rst shut the shutter 8 andthen the shutter 5 and with the other hand first turn the bolt 20, so asto enable the head 22 to pass through the slot 11 of the shutter-plate,and then turn said bolt to the position shown in Fig. 1, so as to secureit in the shutter-recess 9, and consequently securely lock the shuttersin their closed position. To unlock the shutters it is simply necessaryto turn the bolt so as to bring its head 22 in alignment with the slot11 in plate 10 and then draw said head through the plate 1l, when theshutters may be pushed open in the usual manner. Vhen the bolt-head 22has been disengaged from the shutter, it may be drawn into the slot 19of the plate 1S, which it iits snugly, and in this position it willexclude moisture from the interior of the passage 12, and will inconsequence prevent corrosion of the parts of my improvements androtting of the wood forming the window-casing. Vhen the bolthead 22 isdrawn into the slot 19 of plate 18, the downward and inward pitch of thepassage 12 and bolt 2O will prevent said head from casually workin g outof said slot 19 and interfering` with the closing of the shutters.

It will be readily appreciated that while cheap and simple and easy ofapplication my improvements form a very strong and secure lock, and itwill also be appreciated that such lock may be used to advantage inconjunction with those shutt-ers which are opened and closed through themedium of devices in a room without the necessity of raising the window.

Having described my invention, what I claim is- In the shutter fastenerdescribed, the combination of a window casin g havin g a passageextending through it, the bearing plate closing the inner end of saidpassage, the casting 15,r arranged in said passage adgacent to its outerend and having the elongated slot 16, and also having the recess 17, inits outer side, the plate 18, arranged in the sash and in the recess 17,of casting 15, and having the elongated slot 19, disposed at rightangles to the slot 16, of casting 15, screws connecting said plate 18,and the sash, the endwise adjustable locking bolt having the bodyportion 1' arranged in the bearing plate and in the slots 1of casting15, and plate 1S, and having the integral handle or head 21, at itsinner end l and the integral T-head 22, at its outer end and a shutterhaving arecess in its inner side and a slotted plate covering saidrecess; said plate being designed to be engaged by the head 22 of thelocking bolt, all as and for the purpose set forth.

In testimony whereof l affix my signature in presence of two witnesses.
